技术领域Technical field
本申请涉及通信领域，更具体地，涉及一种通信方法和通信装置。The present application relates to the field of communication, and more specifically, to a communication method and communication device.
背景技术Background technique
在802.11ac，电气与电子工程师协会(institute of electrical and electronic engineers，IEEE)无线技术标准中，为无线局域网(wireless fidelity，wifi)信号增加了5GHz频段的设计，这样避免了与蓝牙，微波炉等共用2.4GHz频段产生的信道冲突，改善了用户体验。其中，信标(beacons)帧是wifi信号的一种管理帧，wifi信号可以定时依次按指定间隔发送规律的无线信号(类似心跳)，用于wifi信号源可以与睡眠状态中的终端同步使用。也就是说，一个周期内的beacon帧包括数据发送时段和休眠时段。In the 802.11ac, Institute of Electrical and Electronics Engineers (IEEE) wireless technology standard, a 5GHz band design has been added to the wireless local area network (wireless fidelity, wifi) signal, which avoids sharing with Bluetooth, microwave ovens, etc. The channel conflicts in the 2.4GHz band improve the user experience. Among them, the beacons (beacons) frame is a management frame of the wifi signal. The wifi signal can periodically send regular wireless signals at a specified interval (similar to heartbeat) for the wifi signal source can be used in synchronization with the terminal in the sleep state. That is to say, a beacon frame within one cycle includes a data transmission period and a sleep period.
在终端在接收下行信号(例如，该下行信号为LAA信号)时，若该LAA信号和上述wifi信号共享5GHz频段，则会发生信道冲突。在终端是睡眠状态时，wifi信号源会发类似心跳的beacon帧，wifi信号发送时段只有几十微秒，若LAA信号的信道检测周期较大，持续时间较短则不能完全检测到beacon帧，例如，若LAA信号的信道检测周期最小40ms，持续时间最大70个符号(即5ms)。因此，终端接收LAA信号可能会受到wifi信号的干扰，但是由于终端不能检测到wifi信号，使得LAA信号产生一定的误码率，即资源利用率较低。When the terminal receives a downlink signal (for example, the downlink signal is a LAA signal), if the LAA signal and the wifi signal share a 5 GHz frequency band, channel collision will occur. When the terminal is in the sleep state, the wifi signal source will send a heartbeat-like beacon frame. The wifi signal transmission period is only tens of microseconds. If the channel detection period of the LAA signal is large and the duration is short, the beacon frame cannot be completely detected. For example, if the channel detection period of the LAA signal is at least 40 ms, the duration is at most 70 symbols (that is, 5 ms). Therefore, the terminal may be interfered by the wifi signal when receiving the LAA signal, but because the terminal cannot detect the wifi signal, the LAA signal has a certain bit error rate, that is, the resource utilization rate is low.
发明内容Summary of the invention
本申请提供一种通信方法和通信装置，能够有助于提高资源利用率。The present application provides a communication method and a communication device, which can help to improve resource utilization.

终端通过免授权频谱资源接收LAA信号和wifi信号，并根据该LAA信号和该wifi信号的能量差值确定是否发送上报信息，也就是说，在wifi信号对LAA信号的干扰较大的情况下，向网络设备发送用于指示更新资源分配的上报信息；在wifi信号对LAA信号的干扰较小的情况下，不发送该上报信息。这样有助于网络设备能够合理的进行资源分配，提高了资源利用率，或者说提高了网络设备的吞吐量。The terminal receives the LAA signal and the wifi signal through the unlicensed spectrum resource, and determines whether to send the reported information according to the energy difference between the LAA signal and the wifi signal, that is, in the case where the wifi signal interferes with the LAA signal, Sending reporting information indicating the update of resource allocation to the network device; when the interference of the wifi signal to the LAA signal is small, the reporting information is not sent. This helps network devices to allocate resources reasonably, improves resource utilization, or improves the throughput of network devices.
在一些可能的实现方式中，该根据该LAA信号和该wifi信号的能量差值，确定是否 发送上报信息包括：In some possible implementation manners, the determining whether to send the report information according to the energy difference between the LAA signal and the wifi signal includes:
根据该LAA信号和该wifi信号的能量差值与预设能量差值的大小关系，确定是否发送该上报信息。According to the magnitude relationship between the energy difference between the LAA signal and the wifi signal and the preset energy difference, determine whether to send the reported information.
第一终端可以在该LAA信号的能量和该wifi信号的能量差值大于预设能量差值的情况下发送上报信息，相应地，在小于或等于该预设能量差值的情况下不发送该上报信息。或者第一终端可以在该LAA信号的能量和该wifi信号的能量差值小于或等于预设能量差值的情况下发送上报信息，相应地，在大于该预设能量差值的情况下不发送该上报信息。也就是说，终端能够根据能量差值与预设能量差值的大小关系确定是否发送上报信息，进而能够有助于网络设备能够合理的进行资源分配，提高了资源利用率，或者说提高了网络设备的吞吐量。The first terminal may send the report information when the energy difference between the energy of the LAA signal and the energy of the wifi signal is greater than the preset energy difference, and correspondingly, do not send the report when the energy difference is less than or equal to the preset energy difference Report information. Or the first terminal may send the report information when the energy difference between the energy of the LAA signal and the energy of the wifi signal is less than or equal to the preset energy difference, and accordingly, do not send when the energy difference is greater than the preset energy difference The report information. In other words, the terminal can determine whether to send the report information according to the magnitude relationship between the energy difference and the preset energy difference, which can help the network device to allocate resources reasonably, improve resource utilization, or improve the network Device throughput.
在一些可能的实现方式中，该根据该LAA信号和该wifi信号的能量差值与预设能量差值的大小关系，确定是否发送该上报信息包括：In some possible implementation manners, the determining whether to send the reported information according to the magnitude relationship between the energy difference between the LAA signal and the wifi signal and the preset energy difference includes:
在该LAA信号和该wifi信号的能量差值大于该预设能量差值的情况下，发送该上报信息。When the energy difference between the LAA signal and the wifi signal is greater than the preset energy difference, the report information is sent.
在一些可能的实现方式中，该预设能量差值为该LAA信号的预设误码率对应的能量差值。In some possible implementation manners, the preset energy difference value is the energy difference value corresponding to the preset bit error rate of the LAA signal.
不同的LAA信号的能量和wifi信号的能量的能量差值对应不同LAA信号的误码率，该预设能量差值可以是用户需求的误码率对应的能量差值，这样终端能够需求的误码率对应的能量差值确定是否发送上报信息，从而更进一步有助于网络设备能够合理的进行资源分配，更进一步提高了资源利用率。The energy difference between the energy of different LAA signals and the energy of the wifi signal corresponds to the bit error rate of different LAA signals. The preset energy difference may be the energy difference corresponding to the bit error rate required by the user, so that the terminal can The energy difference corresponding to the code rate determines whether to send the reported information, which further helps the network equipment to reasonably allocate resources and further improves the resource utilization rate.
在一些可能的实现方式中，该wifi信号为周期性发送的，该方法还包括：In some possible implementations, the wifi signal is sent periodically, and the method further includes:
确定该wifi信号在一个周期内的休眠时段；Determine the sleep period of the wifi signal in a cycle;
其中，该上报信息携带该休眠时段。Wherein, the reported information carries the sleep period.
若wifi信号为周期性发送的，则第一终端根据多个周期确定出该wifi信号的发送时段和休眠时段。若该发送时段为协议约定的值，则在上报信息中可以只携带该休眠时段，从而减少上报信息的信令开销。If the wifi signal is sent periodically, the first terminal determines the transmission period and the sleep period of the wifi signal according to multiple cycles. If the sending period is a value stipulated in the protocol, only the sleep period may be carried in the reported information, thereby reducing the signaling overhead of the reported information.
在一些可能的实现方式中，该wifi信号为周期性发送的，该方法还包括：In some possible implementations, the wifi signal is sent periodically, and the method further includes:
确定该wifi信号在一个周期内的发送时段和休眠时段；Determine the sending period and sleeping period of the wifi signal in a cycle;
其中，该上报信息携带该休眠时段和该发送时段。Wherein, the reported information carries the sleep period and the sending period.
若wifi信号为周期性发送的，则第一终端根据多个周期确定出该wifi信号的发送时段和休眠时段。此外，在wifi信号的发送时段并不是第一终端和网络设备约定的情况下，在上报信息中携带该wifi信号的休眠时段和该wifi信号的发送时段，从而使得网络设备更准确的获知wifi信号的发送时段，更进一步有助于提高资源利用率。If the wifi signal is sent periodically, the first terminal determines the transmission period and the sleep period of the wifi signal according to multiple cycles. In addition, in the case where the transmission period of the wifi signal is not agreed between the first terminal and the network device, the sleeping period of the wifi signal and the transmission period of the wifi signal are carried in the reported information, thereby enabling the network device to learn the wifi signal more accurately The sending period of time further helps to improve resource utilization.
在一些可能的实现方式中，该方法还包括：In some possible implementations, the method further includes:

将该LAA信号的RSSI与该wifi信号的RSSI的差值，确定为该LAA信号和该wifi信号的能量差值。The difference between the RSSI of the LAA signal and the RSSI of the wifi signal is determined as the energy difference between the LAA signal and the wifi signal.
第一终端接收单独的LAA信号并确定LAA信号的RSSI，在有干扰的情况下，第一 终端接收到的信号的RSSI值逐渐增大，即第一终端能够确定出接收到的wifi信号和LAA信号的混合信号的能量，以及单独接收到LAA信号的能量，根据二者的差值确定出接收到的wifi信号的能量，进而确定出LAA信号和wifi信号的能量差值，这样终端能够根据该能量差值确定是否发送上报信息，进而能够有助于网络设备能够合理的进行资源分配，提高了资源利用率，或者说提高了网络设备的吞吐量。The first terminal receives a separate LAA signal and determines the RSSI of the LAA signal. In the case of interference, the RSSI value of the signal received by the first terminal gradually increases, that is, the first terminal can determine the received wifi signal and LAA The energy of the mixed signal of the signal and the energy of the LAA signal alone are determined according to the difference between the two to determine the energy of the received wifi signal, and then determine the energy difference between the LAA signal and the wifi signal, so that the terminal can The energy difference determines whether to send the reported information, which can help the network device to reasonably allocate resources, improve resource utilization, or increase the throughput of the network device.
在一些可能的实现方式中，该方法还包括：In some possible implementations, the method further includes:

终端根据该干扰测量信令启动wifi信号测量可以是一接收到干扰测量信令就立即启动wifi信号测量，或者间隔预设时段之后启动wifi信号测量。启动wifi信号测量可以是确定LAA信号的RSSI和wifi信号的RSSI，避免了在网络设备不需要进行干扰测量时，终端主动进行干扰测量造成的资源浪费，从而节省了资源开销。The terminal starting the wifi signal measurement according to the interference measurement signaling may be to start the wifi signal measurement as soon as the interference measurement signaling is received, or to start the wifi signal measurement after a preset period of time. Starting the wifi signal measurement may be to determine the RSSI of the LAA signal and the RSSI of the wifi signal, which avoids the waste of resources caused by the terminal actively performing interference measurement when the network device does not need to perform interference measurement, thereby saving resource overhead.
在一些可能的实现方式中，该干扰测量指令携带至少一个该wifi信号的休眠时段与至少一个映射关系的对应关系，该至少一个映射关系中的每个映射关系为至少一个能量差值与至少一个误码率的映射关系。In some possible implementation manners, the interference measurement instruction carries a correspondence between at least one sleep period of the wifi signal and at least one mapping relationship, and each mapping relationship in the at least one mapping relationship is at least one energy difference and at least one Bit error rate mapping relationship.
该映射关系可以是一个表格，即每个映射关系为包括多个能量差值与多个误码率的一一对应的对应关系的一个表格。此外，不同wifi信号的休眠时段分别对应一个表格，即干扰测量信令可以携带wifi信号的多种休眠时段对应的多个表格。这样第一终端可以根据wifi信号的休眠时段，确定对应的表格。也就是说，第一终端在确定出wifi信号的休眠时段之后，再根据该休眠时段对应的表格确定需求的预设误码率对应的预设能量差值，这样终端能够根据该能量差值确定是否发送上报信息，进而更进一步能够有助于网络设备能够合理的进行资源分配，提高了资源利用率，或者说提高了网络设备的吞吐量。The mapping relationship may be a table, that is, each mapping relationship is a table that includes a one-to-one correspondence between multiple energy difference values and multiple bit error rates. In addition, the sleep periods of different wifi signals respectively correspond to one table, that is, the interference measurement signaling can carry multiple tables corresponding to multiple sleep periods of the wifi signal. In this way, the first terminal can determine the corresponding table according to the sleep period of the wifi signal. In other words, after determining the sleep period of the wifi signal, the first terminal determines the preset energy difference corresponding to the required preset error rate according to the table corresponding to the sleep period, so that the terminal can determine the energy difference according to the energy difference Whether to send the report information, and then further can help the network device to reasonably allocate resources, improve the resource utilization rate, or improve the throughput of the network device.

The communication system in FIG. 1 may include at least one terminal (for example, terminal 10, terminal 20, terminal 30, terminal 40, terminal 50, and terminal 60) and network device 70. The network device 70 is used to provide a communication service for the terminal and access the core network. The terminal can access the network by searching for synchronization signals, broadcast signals, etc. sent by the network device 70 to communicate with the network. The terminal 10, the terminal 20, the terminal 30, the terminal 40, and the terminal 60 in FIG. 1 may perform uplink and downlink transmission with the network device 70.

The terminal 60 can send a downlink signal to the terminal 40 and the terminal 50, and can also receive an uplink signal sent by the terminal 40 and the terminal 50.
图2是本申请一个应用场景的示意图。如图2所示，网络设备在与终端通过进行通信时，wifi信号源也在与终端通过beacon帧进行通信，这样网络设备与终端设备之间的通信可能会受到beacon帧的干扰，使得终端接收网络设备发送的信号的误码率较高，即终端和网络设备之间通信占用资源的资源利用率不高。2 is a schematic diagram of an application scenario of this application. As shown in Figure 2, when the network device communicates with the terminal, the wifi signal source also communicates with the terminal through the beacon frame, so that the communication between the network device and the terminal device may be interfered by the beacon frame, causing the terminal to receive The bit error rate of the signal sent by the network device is high, that is, the resource utilization rate of resources occupied by communication between the terminal and the network device is not high.
例如，在一个特定的场所(例如，旅游区)，wifi信号源可以看作是很多游客子集携带的wifi热点，终端可以看作用户的手机。由于在旅游观光过程中使用wifi的时间累积起来很短，大部分wifi热点处于睡眠侦听态，每个wifi信号对手机接收基站发送的下行信号造成干扰。也就是说，由于wifi信号的干扰，使得手机信号的误码率较高，即手机和基站之间通信占用资源的资源利用率不高。For example, in a specific place (for example, a tourist area), the wifi signal source can be regarded as a wifi hotspot carried by many subsets of tourists, and the terminal can be regarded as the user's mobile phone. Since the time of using wifi in the process of traveling and sightseeing is accumulated very short, most of the wifi hotspots are in sleep listening state, and each wifi signal causes interference to the mobile phone to receive the downlink signal sent by the base station. In other words, due to the interference of the wifi signal, the bit error rate of the mobile phone signal is high, that is, the resource utilization rate of the communication occupied resource between the mobile phone and the base station is not high.
可选地，终端和网络设备之间的通信可以是采用免授权辅助接入(licensed assisted access，LAA)进行通信，及终端接收的网络设备发送的信号可以是LAA信号。例如，如图3所示，LAA仅支持下行业务，且为辅小区，与授权频谱上的主小区一起以载波聚合的形式提供服务。Optionally, the communication between the terminal and the network device may be licensed-assisted access (LAA), and the signal received by the terminal from the network device may be a LAA signal. For example, as shown in FIG. 3, LAA only supports downlink services and is a secondary cell that provides services in the form of carrier aggregation with the primary cell on the licensed spectrum.
需要说明的是，终端和网络设备之间可以是通过LAA信号进行通信，LAA信号可以是LAA帧。LAA帧的结构为帧结构类型3(frame structure type3)，每个LAA帧包括多个数据子帧(data burst)，相邻数据子帧之间可能不连续。It should be noted that the communication between the terminal and the network device may be through a LAA signal, and the LAA signal may be a LAA frame. The structure of the LAA frame is frame structure type 3 (frame structure type 3), each LAA frame includes multiple data subframes (data bursts), and adjacent data subframes may not be continuous.

In addition, in the case where the interfering device is a network device, the network device sending the wifi signal may be the same as the network device sending the LAA signal, that is, the LAA signal sent by one network device is interfered by other signals sent by the network device.
需要说明的是，步骤401和步骤402可以是同时发送给第一终端的。It should be noted that step 401 and step 402 may be sent to the first terminal at the same time.

In addition, the first terminal receives the wifi signal and can determine the energy of the received wifi signal. When the difference between the energy of the LAA signal and the energy of the wifi signal satisfies certain conditions, the first terminal can send the reported information.

Or the first terminal may send the report information when the energy difference between the energy of the LAA signal and the energy of the wifi signal is less than or equal to the preset energy difference, and accordingly, do not send when the energy difference is greater than the preset energy difference The report information.
可选地，预设能量差值可以是该LAA信号的预设误码率对应的能量差值。Optionally, the preset energy difference may be the energy difference corresponding to the preset bit error rate of the LAA signal.
具体地，不同的LAA信号的能量和wifi信号的能量的能量差值对应不同LAA信号的误码率，该预设能量差值可以是用户需求的误码率对应的能量差值。Specifically, the energy difference between the energy of different LAA signals and the energy of the wifi signal corresponds to the bit error rate of different LAA signals, and the preset energy difference may be the energy difference corresponding to the bit error rate required by the user.
例如，在MCS取27时，第一终端可以预先测量不同的能量差值与wifi信号的误码率的对应关系，其中具体取值可以如下述表1所示。这样第一终端可以根据需求的误码率确定预设能量差值。For example, when the MCS takes 27, the first terminal may measure the correspondence between different energy differences and the bit error rate of the wifi signal in advance. The specific values may be as shown in Table 1 below. In this way, the first terminal can determine the preset energy difference according to the required bit error rate.

应理解，该预设误码率可以是第一终端允许的最大误码率，也可以是误码率达到百分之百。It should be understood that the preset bit error rate may be the maximum bit error rate allowed by the first terminal, or it may be that the bit error rate reaches 100%.
可选地，LAA信号的能量和wifi信号的能量可以通过LAA信号的接收信号强度指示(received signal strength indicator，RSSI)和wifi信号的RSSI表示，这样第一终端可以根据该LAA信号的RSSI和wifi信号的RSSI的差值确定是否发送上报信息。Optionally, the energy of the LAA signal and the energy of the wifi signal can be expressed by the received signal strength indicator (RSSI) of the LAA signal and the RSSI of the wifi signal, so that the first terminal can use the RSSI and wifi of the LAA signal The RSSI difference of the signal determines whether to send the report information.
需要说明的是，终端进行确定LAA信号的RSSI或wifi信号的RSSI，可以是由终端中的测量模块执行的。其中，测量模块可以是物理层的模块。It should be noted that the terminal determines the RSSI of the LAA signal or the RSSI of the wifi signal, which may be performed by the measurement module in the terminal. The measurement module may be a module at the physical layer.
可选地，第一终端确定wifi信号的RSSI可以是根据接收到的wifi信号和LAA信号的混合在一起的信号的RSSI和单独接收LAA信号的RSSI的差值得到的。Optionally, the first terminal determining the RSSI of the wifi signal may be obtained according to the difference between the RSSI of the mixed signal of the received wifi signal and the LAA signal and the RSSI of the LAA signal alone.
具体地，第一终端接收单独的LAA信号并确定LAA信号的RSSI，在有干扰的情况下，第一终端接收到的信号的RSSI值逐渐增大，即第一终端能够确定出接收到的wifi信号和LAA信号的混合信号的能量，以及单独接收到LAA信号的能量，根据二者的差值确定出接收到的wifi信号的能量，进而确定出LAA信号和wifi信号的能量差值。Specifically, the first terminal receives a separate LAA signal and determines the RSSI of the LAA signal. In the case of interference, the RSSI value of the signal received by the first terminal gradually increases, that is, the first terminal can determine the received WiFi The energy of the mixed signal of the signal and the LAA signal, and the energy of the separately received LAA signal, determine the energy of the received wifi signal according to the difference between the two, and then determine the energy difference between the LAA signal and the wifi signal.
例如，如图5所示，LAA信号的能量为RSSI，LAA信号和wifi信号混合的能量为RSSI1，则wifi信号的能量为RSSI1-RSSI，LAA信号和wifi信号的能量差为RSSI-(RSSI1-RSSI)。For example, as shown in Figure 5, the energy of the LAA signal is RSSI, the energy of the LAA signal and the wifi signal is RSSI1, the energy of the wifi signal is RSSI1-RSSI, and the energy difference between the LAA signal and the wifi signal is RSSI- (RSSI1- RSSI).
需要说明的是，对于多个发送时段不同的wifi信号，终端可以分别确定每个wifi信号对LAA信号的影响，即分别确定LAA信号和各个wifi信号的能量差值。It should be noted that, for multiple wifi signals with different transmission periods, the terminal may separately determine the influence of each wifi signal on the LAA signal, that is, the energy difference between the LAA signal and each wifi signal.

具体地，终端根据该干扰测量信令启动wifi信号测量可以是一接收到干扰测量信令就立即启动wifi信号测量，或者间隔预设时段之后启动wifi信号测量。启动wifi信号测量可以是确定LAA信号的RSSI和wifi信号的RSSI。Specifically, the terminal starting the wifi signal measurement according to the interference measurement signaling may be to start the wifi signal measurement as soon as the interference measurement signaling is received, or to start the wifi signal measurement after a preset period of time. Starting the wifi signal measurement may be to determine the RSSI of the LAA signal and the RSSI of the wifi signal.
可选地，该干扰测量信令携带至少一个wifi信号的休眠时段与至少一个映射关系的对应关系，该至少一个映射关系中的每个映射关系为至少一个能量差值与至少一个误码率的映射关系。Optionally, the interference measurement signaling carries a correspondence between the sleep period of at least one wifi signal and at least one mapping relationship, and each mapping relationship in the at least one mapping relationship is at least one energy difference and at least one bit error rate Mapping relations.
具体地，该映射关系可以是一个表格，即每个映射关系为包括多个能量差值与多个误码率的一一对应的对应关系的一个表格。此外，不同wifi信号的休眠时段分别对应一个表格，即干扰测量信令可以携带wifi信号的多种休眠时段对应的多个表格。这样第一终端可以根据wifi信号的休眠时段，确定对应的表格。也就是说，第一终端在确定出wifi信号的休眠时段之后，再根据该休眠时段对应的表格确定需求的预设误码率对应的预设能量差值。Specifically, the mapping relationship may be a table, that is, each mapping relationship is a table that includes a one-to-one correspondence between multiple energy difference values and multiple bit error rates. In addition, the sleep periods of different wifi signals respectively correspond to one table, that is, the interference measurement signaling can carry multiple tables corresponding to multiple sleep periods of the wifi signal. In this way, the first terminal can determine the corresponding table according to the sleep period of the wifi signal. That is to say, after determining the sleep period of the wifi signal, the first terminal determines the preset energy difference corresponding to the required preset error rate according to the table corresponding to the sleep period.
需要说明的是，根据wifi信号的休眠时段查找对应的表格可以是终端中的协议栈执行的。It should be noted that searching the corresponding table according to the sleep period of the wifi signal may be performed by the protocol stack in the terminal.
可选地，网络设备还可以根据wifi信号的发送时段的长短，确定发送干扰测量信令的区域。也就是说，wifi信号的发送时段的不同，分别对应不同区域(例如，不同的小区)。这样网络设备可以根据wifi信号的发送时段的长短，向对应的部分区域发送该干扰测量信令。Optionally, the network device may also determine the area to send the interference measurement signaling according to the length of the period of transmission of the wifi signal. That is to say, different transmission periods of wifi signals correspond to different areas (for example, different cells). In this way, the network device can send the interference measurement signaling to the corresponding partial area according to the length of the wifi signal transmission period.

具体地，若wifi信号为周期性发送的，则第一终端根据多个周期确定出该wifi信号的发送时段和休眠时段。例如，若wifi信号的休眠时段为100ms左右，第一终端大概记录20个周期，就能够确定出wifi信号的具体休眠时段的时长。Specifically, if the wifi signal is sent periodically, the first terminal determines the transmission period and the sleep period of the wifi signal according to multiple periods. For example, if the sleep period of the wifi signal is about 100 ms, and the first terminal records about 20 cycles, the duration of the specific sleep period of the wifi signal can be determined.
若该发送时段为协议约定的值，则在上报信息中可以只携带该休眠时段。例如，在802.11a/g标准中beacon帧的发送时段固定为56μs。If the sending period is a value stipulated in the protocol, only the sleeping period may be carried in the reported information. For example, in the 802.11a / g standard, the transmission period of beacon frames is fixed at 56 μs.
需要说明的是，wifi信号的发送时段或休眠时段的确定也可以是第一终端的测量模块执行的。It should be noted that the determination of the transmission period or the sleep period of the wifi signal may also be performed by the measurement module of the first terminal.
可选地，该wifi信号为周期性发送的，则第一终端还可以确定该wifi信号在一个周期内的发送时段和休眠时段，并在该上报信息携带该休眠时段和该wifi信号的发送时段。Optionally, the wifi signal is sent periodically, then the first terminal may also determine the transmission period and the sleep period of the wifi signal within a period, and carry the sleep period and the transmission period of the wifi signal in the report information .

In addition, in the case where the transmission period or the sleep period of the wifi signal is performed by the measurement module of the first terminal, the granularity of the period may be determined by the accuracy of the measurement module.
405，网络设备根据该上报信息，更新资源分配。405. The network device updates the resource allocation according to the reported information.
具体地，网络设备在接收到上报信息后，可以原本用于与第一终端进行通信的资源发送给其他设备，从而有助于提高资源的利用。Specifically, after receiving the reported information, the network device may send the resources originally used for communication with the first terminal to other devices, thereby helping to improve the utilization of resources.

可选地，网络设备在发送LAA信号时还可以启动定时器，在定时器超时之前收到上报信息，则根据该上报信息更新资源分配。若在定时器超时之后才收到上报信息，则不进行资源分配的更新。Optionally, the network device may also start a timer when sending the LAA signal, and if the report information is received before the timer expires, the resource allocation is updated according to the report information. If the report information is received after the timer expires, the resource allocation is not updated.
需要说明的是，该定时器的预设时长的长短可以对应于资源分配的快慢，即定时器的预设时长较大时可以对应于较慢的资源分配，预设时长较短时可以对应于较长的资源分配。可选地，该预设时长可以由该第一终端所处的场景确定，例如，若第一终端处于通信繁忙地段，为了加快资源分配可以设置预设时长较长，若第一终端处于通信空闲地段，可以设置预设时长较短。It should be noted that the preset duration of the timer can correspond to the speed of resource allocation, that is, the preset duration of the timer can be corresponding to the slower resource allocation, and the preset duration can be corresponding to the shorter Longer resource allocation.
